Expanding access to monoclonal antibody-based products A global call to action Wellcome exists to improve health by helping great ideas to thrive. We support researchers, we take on big health challenges, we campaign for better science, and we help everyone get involved with science and health research. We are a politically and financially independent foundation. wellcome.ac.uk IAVI is a nonprofit scientific research organization dedicated to addressing urgent, unmet global health challenges including HIV and tuberculosis. Our mission is to translate scientific discoveries into affordable, globally accessible public health solutions. iavi.org Expanding access to monoclonal antibody-based products A global call to action wellcome.ac.uk iavi.org Executive summary Monoclonal antibodies are one of the most powerful Identifying pathways to provide affordable, timely tools in modern medicine. More than 100 of them and sustainable access to monoclonal antibody- have been licensed over the past 30 years and they based products across the globe is therefore a are transforming the way doctors treat, prevent and global health priority. even cure serious non-communicable diseases, including many cancers and autoimmune disorders. There is not a simple solution to this problem. These monoclonal antibody products are significantly Monoclonal antibodies are more complex and more effective than previously available therapies expensive to develop and produce than small and are often better tolerated and easier to deliver. molecule generic drugs. And the business and There’s also a rapidly growing pipeline of monoclonal partnership models that have vastly expanded antibodies to treat and prevent many existing and global access to some HIV drugs are not necessarily emerging infectious and neglected diseases. applicable or sufficient. Ensuring monoclonal antibodies are available and affordable globally Millions of people around the world stand to will require new ways of thinking, new types of benefit both from existing monoclonal antibody- collaboration and new ways of doing business. based products and those in development. Rates of non-communicable diseases are on the rise in This report identifies a series of parallel actions many developing countries.

As advances are applied throughout the process of the COVID-19 pandemic has shown, no country is identifying, optimising, producing and delivering immune to the threat posed by emerging infectious more potent, lower-cost monoclonal antibody diseases. If monoclonal antibodies prove to be products. New business models that promote the effective for COVID-19, ensuring prompt, equitable availability and affordability of these products are and affordable global access to these products, as also necessary. Together, these actions will make it well as others, will be imperative. possible to address the growing inequity to these products, saving or improving millions of lives in the But as this report details, global access to process. monoclonal antibody products is now severely limited in many countries. Today, the market for Progress can’t come soon enough. The goal of this monoclonal antibodies is overwhelmingly in high- report is to catalyse discussion, collaboration and income countries. Few, if any, monoclonal antibodies action. Pharmaceutical companies, global health are registered in low-income countries, and those agencies, public sector entities, philanthropic that are registered in many middle-income countries organisations and ministries of health must join are often unavailable in their public health systems, forces to make global access to transformative making them prohibitively expensive.

The classification of low-, middle- and high-income countries is based on World Bank classifications. The report highlights opportunities for expanding access to monoclonal antibodies for cancers and autoimmune diseases, as well as those for neglected and viral/bacterial infectious diseases that are anticipated to represent a significant percentage of the future antibody market. These include antibodies against SARS-CoV-2, HIV, respiratory syncytial virus (RSV), rabies, Ebola, filoviruses, viral enteric pathogens and gram negative bacterial enteric pathogens, including E.coli, Klebsiella p., Shigella and Salmonella, which are on the World Health Organization’s (WHO) and the US Centers for Disease Control and Prevention’s lists of critical drug-resistant pathogens, as well as gram-positive bacterial enteric pathogens such as C. difficile. Approach, data collection and analyses were monoclonal antibodies to illustrate the impact they based on two methods. A robust assessment was have had on non-communicable, communicable conducted of peer-reviewed biomedical literature, and neglected diseases, and to evaluate the news sources, organisational websites, drug availability of the products and their impact in labels, recognised global and national datasets high-, middle- and low-income countries for which (including those available from the Institute for data are available.
